hi,

Enqueue is used to lock the object so it is used before locking. like ENQUEUE_EKBLK FM is for Request lock for object EKBLK

To release the lock use dequeue.

Hi Nisha,

For each ock object that exist in the database, there will be two function modules that get generated (One enque<your lockobject name> and one deque*<your lockobject name>).

You proceed in this sequence.

call function 'ENQUE....

*Do your update/modify/insert/delete on database tables

call function 'DEQUE...

Regards,

Ravi

Hi,

We will use Enqueue and Dequeue FM's to lock the table and unlock the table .

FM's :

ENQUEUE_E_TABLE - use before updating the data to a table

DEQUEUE_E_TABLE - use after updating the data to a table

Regards

actually the problem is i got a caswe in which the whole table was getting locked and not a particular record so what may be the reason.i also included the key fields inside the lock.
